Answer:
White: A---
Black: aaB-
Brown: aabb
Explanation:
As per given information, the genotype of parent white sheep is AaBb (heterozygous white).
The gene "A" is dominant over gene "B". Hence, all the genotypes with one or two copies of "A" would exhibit white phenotype.
All the genotypes that have "aa" and one or two "B" alleles would exhibit black phenotype.
All the genotypes with "aabb" allele combination would exhibit brown phenotype.
Answer:
B. Complex multi-cellular organisms will suffer more, because vital differentiated cells that the rest of the organism requires will be lost.
Explanation:
If the predator takes bite of an organism, complex multi-cellular organisms will be likely to suffer more. Multi-cellular organisms have specialized cells that perform specific functions like skin cells, muscle cells, etc. If any part of such organism is lost, the whole body’s mechanism would be harmed.
Answer:
the first one
Explanation:
The animals above it can no longer eat it, and the animals below it will no longer be eaten by it.
Dominant is when an allele of a gene masks a recessive allele.
Answer:
Most protists have mitochondria and chloroplasts. This is statement is true.
Explanation:
Protists are the organisms that are eukaryotes i. e. have true nucleus and made of single cell. Most of the protists contain chloroplast. These protists are green in color due to the presence of chlorophyll that's why they make their own food like plants. Some protists also contains mitochondria which generates energy from the food they eat.
